TS2307: Cannot find module 'class-validator'

Solution 1
Set "moduleResolution": "node"
in your tsconfig.json
:
{
"compilerOptions": {
"experimentalDecorators": true,
"moduleResolution": "node",
"noImplicitAny": true,
"target": "es6"
}
}
You can find more info on how TypeScript resolves your imported modules here: https://www.typescriptlang.org/docs/handbook/module-resolution.html#node
Solution 2
This worked for me: yarn add graphql class-validator type-graphql

Solution 3
You need to install typescript types for validator in addition to installing class-validator.
That is npm install @types/validator

I'm attempting to use the class-validator module in a typescript project. However when I compile typescript issues the following warning:
src/main/ts/domain/Order.ts(1,48): error TS2307: Cannot find module 'class-validator'.
The line it is complaining about looks like this:
import { IsInt, IsNotEmpty, IsDate, Min } from "class-validator";
I have gulp setup like this:
var gulp = require('gulp'); var ts = require('gulp-typescript'); var tsProject = ts.createProject("tsconfig.json"); gulp.task('default', function() { return tsProject.src() .pipe(tsProject()) .js.pipe(gulp.dest("target/main/js")); });
And my tsconfig.json looks like this:
{ "files": [ "src/main/ts/**/*.ts" ], "compilerOptions": { "experimentalDecorators": true, "noImplicitAny": true, "target": "es6" } }
Thoughts?
